В настоящее время я разрабатываю приложение RESTful на основе трикотажа и хотел бы использовать DPI в своих ресурсах. (Примечание: версия Джерси 2.23.1 и контейнер сервлетов является кот 8.5.3.)Ошибка HK2 была обнаружена в коде, который не работает в активной области ошибки Джерси
Поэтому я последовал за учебник Chapter 23. Custom Injection and Lifecycle Management в джерси документы и создали ресурс, завод и связать фабрику класса как это:
Ресурс:
@Path("/{project}/catalogs")
public class ProjectsResource {
@Inject
Project project;
...
}
Фабрика:
public class ProjectFactory extends Factory<Project> {
private final Cache cache = cache.getInstance();
@PathParam("project")
private String project;
private HttpServletRequest request;
@Inject
public ProjectFactory(HttpServletRequest request) {
this.request = request;
}
@Override
public Project provide() {
return cache.get(project, Project.class);
}
@Override
public void dispose(Project instance) {}
}
Также у меня есть функция, которая регистрирует AbstractBinder, который связывает мой ProjectFactory с моим классом Project.
@Provider
public class ProjectFeature implements Feature {
@Override
public boolean configure(FeatureContext context) {
context.register(new AbstractBinder() {
@Override
protected void configure() {
bindFactory(ProjectFactory.class)
.to(Project.class)
.proxy(false)
.proxyForSameScope(true)
.in(RequestScoped.class);
});
return true;
}
}
Реально проблема, когда я называю мой ресурс все в порядке и я могу получить доступ к экземпляру проекта, но в моем TOMCAT Catalina журналов я получаю следующие Свайные след:

Любые идеи, как я могу решить эти предупреждения?
Это похоже на ошибку в Джерси для меня, вы должны сообщить об этом здесь: https://java.net/jira/browse/JERSEY/?selectedTab=com.atlassian.jira.jira-projects-plugin:summary -panel – jwells131313
Спасибо за ваш совет. Я сообщил об этой ошибке здесь: https://java.net/jira/browse/JERSEY-3141 –
